Hi Santosh,

Could you provide some sample code so that we can try to reproduce the issue locally?

Hi Bozhidar,
I had solved this problem by using RadAjaxPanel,
But now my main problem is RadListbox item is not transferring to destination Radlistbox after publishing in to IIS 6,
but transfer functionality is working fine locally in my Visual studio 2010 and no build errors at locally.

aspx Code:

 <telerik:RadAjaxPanel ID="radajaxpnlMain" runat="server">
<telerik:RadListBox runat="server" ID="RadListBoxSource" OnItemDataBound="RadListBoxSource_ItemDataBound"
 OnTransferring="RadListBoxSource_Transferring" AllowTransferOnDoubleClick="true"
AutoPostBack="true" EnableDragAndDrop="false" AllowTransfer="true" SelectionMode="Multiple"
TransferToID="RadListBoxDestination" AutoPostBackOnTransfer="true" Skin="WebBlue"
OnSelectedIndexChanged="RadListBoxSource_SelectedIndexChanged">
</telerik:RadListBox>
                               
<telerik:RadListBox runat="server" ID="RadListBoxDestination" AllowTransferOnDoubleClick="true"
AllowTransferDuplicates="false" EnableDragAndDrop="false"
OnSelectedIndexChanged="RadListBoxDestination_SelectedIndexChanged" Skin="WebBlue"
SelectionMode="Multiple" OnItemDataBound="RadListBoxDestination_ItemDataBound"
AutoPostBack="true" AutoPostBackOnTransfer="true">
</telerik:RadListBox>
</telerik:RadAjaxPanel>



Please Support.
